Fatal Error 7105 ... text, ntext, or image node does not exist

I'm getting the following in error in Enterprise Manager:
Fatal Error 7105 ... text, ntext, or image node does not exist
It seems that a row in a table has become corrupt or something because when
I try to query for that row or scroll down in the table to view the row (the
preceding rows display fine), that is when I get this error. Can a row that
causes this error be salvaged or deleted or something? It seems it is this
one row that is causing the problem. Is that right?
I found this KB article that suggests applying a hotfix.
http://support.microsoft.com/kb/890755
The hotfix seems to have come out between SP 3a & SP 4. I already have
Service Pack 4 installed, so I'm wondering if this proposed hotfix is already
part of SP 4 or if I should try to apply the hotfix?
I don't want to mess up my box, but I need this error resolved.
If anyone can offer furter advice, I would appreciated (and then I can get a
broken app back up and running).
Thanks
I have a correction to my post.
I'm getting the following error in Enterprise Manager:
[Microsoft][ODBC SQL Server Driver][SQL Server]Page (1:6890), slot 35 for
text, ntext, or image node does not exist.
In my web app, the error is:
Fatal Error 7105 ... text, ntext, or image node does not exist
